       "A small batch of fixes, about 50% tagged for stable and the rest for
        recently merged code.
        There's one more fix for the >128T handling on hash. Once a process
        had requested a single mmap above 128T we would then always search
        above 128T. The correct behaviour is to consider the hint address in
        isolation for each mmap request.
        Then a couple of fixes for the IMC PMU, a missing EXPORT_SYMBOL in
        VAS, a fix for STRICT_KERNEL_RWX on 32-bit, and a fix to correctly
        identify P9 DD2.1 but in code that is currently not used by default.

      David Howells authored
      Fix some of dentry handling in AFS directory ops:
       (1) Do d_drop() on the new_dentry before assigning a new inode to it in
           afs_vnode_new_inode().  It's fine to do this before calling afs_iget()
           because the operation has taken place on the server.
       (2) Replace d_instantiate()/d_rehash() with d_add().
       (3) Don't d_drop() the new_dentry in afs_rename() on error.
      Also fix afs_link() and afs_rename() to call key_put() on all error paths
      where the key is taken.

      afs: Make afs_write_begin() avoid writing to a page that's being stored · 5a039c32
      David Howells authored
      Make afs_write_begin() wait for a page that's marked PG_writeback because:
       (1) We need to avoid interference with the data being stored so that the
           data on the server ends up in a defined state.
       (2) page->private is used to track the window of dirty data within a page,
           but it's also used by the storage code to track what's being written,
           being cleared by the completion notification.  Ownership can't be
           relinquished by the storage code until completion because it a store
           fails, the data must be remarked dirty.
      Tracing shows something like the following (edited):

      sched/debug: Fix task state recording/printout · 3f5fe9fe
      Thomas Gleixner authored
      The recent conversion of the task state recording to use task_state_index()
      broke the sched_switch tracepoint task state output.
      task_state_index() returns surprisingly an index (0-7) which is then
      printed with __print_flags() applying bitmasks. Not really working and
      resulting in weird states like 'prev_state=t' instead of 'prev_state=I'.
      Use TASK_REPORT_MAX instead of TASK_STATE_MAX to report preemption. Build a
      bitmask from the return value of task_state_index() and store it in
      entry->prev_state, which makes __print_flags() work as expected.

      the ModR/M Byte (bits 2,1,0 in parenthesis)"
      In that table, opcodes listed by the index REG bits as:
        000         001       010 011  100        101        110         111

      Borislav Petkov authored
      In order to save on redundant structs definitions
      insn_get_code_seg_params() was made to return two 4-bit values in a char
      but clang complains:
        arch/x86/lib/insn-eval.c:780:10: warning: implicit conversion from 'int' to 'char'
      	  changes value from 132 to -124 [-Wconstant-conversion]
                        return INSN_CODE_SEG_PARAMS(4, 8);
                        ~~~~~~ ^~~~~~~~~~~~~~~~~~~~~~~~~~
        ./arch/x86/include/asm/insn-eval.h:16:57: note: expanded from macro 'INSN_CODE_SEG_PARAMS'
        #define INSN_CODE_SEG_PARAMS(oper_sz, addr_sz) (oper_sz | (addr_sz << 4))
      Those two values do get picked apart afterwards the opposite way of how
      they were ORed so wrt to the LSByte, the return value is the same.
      But this function returns -EINVAL in the error case, which is an int. So
      make it return an int which is the native word size anyway and thus fix
      the clang warning.

      Intel Wired LAN Driver Fixes 2017-11-21
      This series contains fixes for igb/vf, ixgbe/vf, i40e/vf and fm10k.
      Jake fixes a regression issue with older firmware, where we were using
      the NVM lock to synchronize NVM reads for all devices and firmware
      versions, yet this caused issues with older firmware prior to version
      1.5.  Fixed this by only grabbing the lock for newer devices and firmware
      version 1.5 or newer.
      Zijie Pan fixes the calculation of the i40e VF MAC addresses, where it was
      possible to increment to the next MAC entry without calling
      Amritha removes the upper limit of 64 queues on a channel VSI since the
      upper bound is determined by the VSI's num_queue_pairs.
      Filip fixes an issue during FLR resets, where should have been checking
      for upcoming core reset and if so, just return with I40E_ERR_NOT_READY.
      Alan fixes the notifying clients of l2 parameters by copying the
      parameters to the client instance struct and re-organizes the priority
      in which the client tasks fire so that if the flag for notifying l2
      params is set, it will trigger before the client open task.  Also fixed
      the promiscuous settings after reset for all the VSI's.
      Brian King from IBM fixes an issue seen on Power systems which would
      result in skb list corruption and eventual kernel oops.  Brian
      provides the same fix for nearly all our drivers, to replace the
      read_barrier_depends with smp_rmb() to ensure loads are ordered with
      respect to the load of tx_buffer->next_to_watch.

      net: dsa: bcm_sf2: Clear IDDQ_GLOBAL_PWR bit for PHY · 4b52d010
      Florian Fainelli authored
      The PHY on BCM7278 has an additional bit that needs to be cleared:
      IDDQ_GLOBAL_PWR, without doing this, the PHY remains stuck in reset out
      of suspend/resume cycles.
      Fixes: 0fe99338 ("net: dsa: bcm_sf2: Add support for BCM7278 integrated switch")

      pull-request: bpf 2017-11-23
      The following pull-request contains BPF updates for your *net* tree.
      The main changes are:
      1) Several BPF offloading fixes, from Jakub. Among others:
          - Limit offload to cls_bpf and XDP program types only.
          - Move device validation into the driver and don't make
            any assumptions about the device in the classifier due
            to shared blocks semantics.
          - Don't pass offloaded XDP program into the driver when
            it should be run in native XDP instead. Offloaded ones
            are not JITed for the host in such cases.
          - Don't destroy device offload state when moved to
            another namespace.
          - Revert dumping offload info into user space for now,
            since ifindex alone is not sufficient. This will be
            redone properly for bpf-next tree.
      2) Fix test_verifier to avoid using bpf_probe_write_user()
         helper in test cases, since it's dumping a warning into
         kernel log which may confuse users when only running tests.
         Switch to use bpf_trace_printk() instead, from Yonghong.
      3) Several fixes for correcting ARG_CONST_SIZE_OR_ZERO semantics
         before it becomes uabi, from Gianluca. More specifically:
          - Add a type ARG_PTR_TO_MEM_OR_NULL that is used only
            by bpf_csum_diff(), where the argument is either a
            valid pointer or NULL. The subsequent ARG_CONST_SIZE_OR_ZERO
            then enforces a valid pointer in case of non-0 size
            or a valid pointer or NULL in case of size 0. Given
            that, the semantics for ARG_PTR_TO_MEM in combination
            with ARG_CONST_SIZE_OR_ZERO are now such that in case
            of size 0, the pointer must always be valid and cannot
            be NULL. This fix in semantics allows for bpf_probe_read()
            to drop the recently added size == 0 check in the helper
            that would become part of uabi otherwise once released.
            At the same time we can then fix bpf_probe_read_str() and
            bpf_perf_event_output() to use ARG_CONST_SIZE_OR_ZERO
            instead of ARG_CONST_SIZE in order to fix recently
            reported issues by Arnaldo et al, where LLVM optimizes
            two boundary checks into a single one for unknown
            variables where the verifier looses track of the variable
            bounds and thus rejects valid programs otherwise.
      4) A fix for the verifier for the case when it detects
         comparison of two constants where the branch is guaranteed
         to not be taken at runtime. Verifier will rightfully prune
         the exploration of such paths, but we still pass the program
         to JITs, where they would complain about using reserved
         fields, etc. Track such dead instructions and sanitize
         them with mov r0,r0. Rejection is not possible since LLVM
         may generate them for valid C code and doesn't do as much
         data flow analysis as verifier. For bpf-next we might
         implement removal of such dead code and adjust branches
         instead. Fix from Alexei.
